Kiesha wants to know what type of food wolves prefer to eat. To answer her question, she attaches a small video camera around a wolf's neck, allows the wolf to go about its normal activities for one week, and then makes notes when she later observes the video.

Kirk also wants to know what type of food wolves prefer to eat. However, Kirk chooses to perform a controlled experiment. In Kirk's experiment, he keeps a wolf in captivity, offers the wolf four different selections of food each day, and records which food item the wolf selected.

What is one disadvantage of Keisha's investigation?
A.
Keisha's investigation is not a valid method of scientific inquiry.

B.
Keisha's observations are less true to life than Kirk's observations.

C.
Keisha is not able to completely control all the variables within her investigation.

D.
Keisha's observations will not result in the formation of a conclusion.

if you tell me the video, i may be able to answer your question.

a.indigo and cochineal

b.animal hides

c.silver and gold

e.cacao beans and sugarcane

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
